Abstract

The invention discloses a COD removing agent and a using method thereof, which relates to the technical field of sewage treatment, the removing agent is prepared from the following raw materials in percentage by weight: 10%-30% of activated carbon, 5%-15% of zeolite powder, 5%-15% of bentonite, 10%-20% of polyaluminum ferric silicate, 10%-20% of polyaluminum ferric sulfate, 10%-20% of polyferroussulfate and 10%-20% of polyferric sulfate. According to the COD removing agent disclosed by the invention, organic pollutants in wastewater can be effectively removed through the synergistic effect ofseven raw materials, namely polysilicate aluminum ferric, polydiacid aluminum ferric, polyferrous sulfate, polyferric sulfate, powdered activated carbon, calcium bentonite and clinoptilolite powder;the COD removing agent is applied to wastewater treatment, the pH value of raw water does not need to be adjusted to be alkaline when the COD removing agent is used, a large amount of alkali raw materials are saved, and the water treatment process is shortened.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a COD remover and a using method thereof. Background technique [0002] COD (Chemical Oxygen Demand) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. The oxygen equivalent of substances (generally organic matter) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. A high chemical oxygen demand means that the water contains a large amount of reducing substances, mainly organic pollutants. The higher the chemical oxygen demand, the more serious the organic pollution in the water. [0003] Coking wastewater is a typical toxic and refractory organic wastewater, which mainly comes from the production water and steam condensation wastewater in the initial cooling of coke oven gas and coking production. In order to effectively control the concentration of or...
